Identification of Violence in the Home - Pediatric and Parental Reports
Objectives: To compare the rates of domestic violence reported by mothers with those identified by physicians, to compare the rates of harsh discipline practices reported by mothers with the rates of abuse identified by physicians, and to examine the relationship between reported domestic violence and harsh discipline practices. Design: Interviews with parents and pediatricians to compare pediatric detection of domestic violence and child abuse with parental reports of domestic violence and harsh discipline practices. Setting: Community-based pediatric practices in the 13-town greater New Haven, Conn, area. Participants: Of the 23 practices invited, 19 agreed to participate. Of the 2006 parents of eligible 4- to 8-year-olds asked to participate, 1886 (94%) completed the Child Behavior Checklist. Of those invited into the interview portion, 1148 (83%) completed the 90-minute in-person interview. Main Outcome Measures: Percentages of cases of domestic violence identified by pediatricians and reported by mothers. Percentages of cases of child abuse detected by pediatricians and percentages of mothers reporting that they have hit their children and left a mark. Results: Pediatricians detected domestic violence in 0.3% of the cases, but parents reported domestic violence in 4.2% (kappa = 0.106 [95% confidence interval, -0.007 to 0.219]). Pediatricians identified physical abuse of children in 0.5% of the cases, while mothers reported hitting their children and leaving a mark in 21.6% (kappa = 0.003 [95% confidence interval, -0.018 to 0.024]). Mothers reporting domestic violence were significantly more likely to report hitting hard enough to leave a mark (relative risk, 1.6 ([95% confidence interval, 1.09-2.38]) compared with those not reporting domestic violence. Physicians identifying domestic violence were not significantly more likely to report child abuse than those not identifying domestic violence. Conclusions: Parents report more cases of violence than pediatricians detect. Pediatricians should ask parents directly about domestic violence and harsh discipline
Does she think sheās supported? Maternal perceptions of their experiences in the neonatal intensive care unit
Parentsā involvement in the care of their infants in the neonatal intensive care unit (NICU) is critically important, leading many NICUs to implement policies and practices of family-centered care (FCC). Analyzing narrative interviews, we examined whether mothers of premature infants who participated in an intervention to help reduce anxiety, stress, and depression felt that their NICU experience reflected four key nursing behaviors previously identified as being necessary to achieving FCC. Fifty-six narratives derived from semi-structured interviews with the mothers were analyzed qualitatively and quantitatively to examine whether the women experienced emotional support, parent empowerment, welcoming environment, and parent education, as well as whether differences in reported experiences were related to sociodemographic factors or maternal coping styles. Overall, the mothers reported more negative than positive experiences with respect to the four behaviors, and those who had negative interactions with the hospital staff felt a sense of disenfranchisement and failure as mothers. Sociodemographic factors and coping styles were significantly associated with the mothersā perceptions of their experiences, although these relationships were not consistent. Achieving actual FCC in the NICU may require parent-informed evidence-based changes in NICU personnel training and infrastructure
Early-Onset Bipolar Spectrum Disorders: Diagnostic Issues
Since the mid 1990s, early-onset bipolar spectrum disorders (BPSDs) have received increased attention in both the popular press and scholarly press. Rates of diagnosis of BPSD in children and adolescents have increased in inpatient, outpatient, and primary care settings. BPSDs remain difficult to diagnose, particularly in youth. The current diagnostic system makes few modifications to accommodate children and adolescents. Researchers in this area have developed specific BPSD definitions that affect the generalizability of their findings to all youth with BPSD. Despite knowledge gains from the research, BPSDs are still difficult to diagnose because clinicians must: (1) consider the impact of the childās developmental level on symptom presentation (e.g., normative behavior prevalence, environmental limitations on youth behavior, pubertal status, irritability, symptom duration); (2) weigh associated impairment and course of illness (e.g., neurocognitive functioning, failing to meet full DSM criteria, future impairment); and (3) make decisions about appropriate assessment (differentiating BPSD from medical illnesses, medications, drug use, or other psychiatric diagnoses that might better account for symptoms; comorbid disorders; informant characteristics and assessment measures to use). Research findings concerning these challenges and relevant recommendations are offered. Areas for further research to guide cliniciansā assessment of children with early-onset BPSD are highlighted
Improving Clinical Prediction of Bipolar Spectrum Disorders in Youth.
This report evaluates whether classification tree algorithms (CTA) may improve the identification of individuals at risk for bipolar spectrum disorders (BPSD). Analyses used the Longitudinal Assessment of Manic Symptoms (LAMS) cohort (629 youth, 148 with BPSD and 481 without BPSD). Parent ratings of mania symptoms, stressful life events, parenting stress, and parental history of mania were included as risk factors. Comparable overall accuracy was observed for CTA (75.4%) relative to logistic regression (77.6%). However, CTA showed increased sensitivity (0.28 vs. 0.18) at the expense of slightly decreased specificity and positive predictive power. The advantage of CTA algorithms for clinical decision making is demonstrated by the combinations of predictors most useful for altering the probability of BPSD. The 24% sample probability of BPSD was substantially decreased in youth with low screening and baseline parent ratings of mania, negative parental history of mania, and low levels of stressful life events (2%). High screening plus high baseline parent-rated mania nearly doubled the BPSD probability (46%). Future work will benefit from examining additional, powerful predictors, such as alternative data sources (e.g., clinician ratings, neurocognitive test data); these may increase the clinical utility of CTA models further
Stability of Satellite Planes in M31 II: Effects of the Dark Subhalo Population
The planar arrangement of nearly half the satellite galaxies of M31 has been
a source of mystery and speculation since it was discovered. With a growing
number of other host galaxies showing these satellite galaxy planes, their
stability and longevity have become central to the debate on whether the
presence of satellite planes are a natural consequence of prevailing
cosmological models, or represent a challenge. Given the dependence of their
stability on host halo shape, we look into how a galaxy plane's dark matter
environment influences its longevity. An increased number of dark matter
subhalos results in increased interactions that hasten the deterioration of an
already-formed plane of satellite galaxies in spherical dark halos. The role of
total dark matter mass fraction held in subhalos in dispersing a plane of
galaxies present non trivial effects on plane longevity as well. But any
misalignments of plane inclines to major axes of flattened dark matter halos
lead to their lifetimes being reduced to < 3 Gyrs. Distributing > 40% of total
dark mass in subhalos in the overall dark matter distribution results in a
plane of satellite galaxies that is prone to change through the 5 Gyr
integration time period.Comment: 11 pages, 9 figures, accepted to MNRAS September 22 201
Comparing the CASI-4R and the PGBI-10Ā M for Differentiating Bipolar Spectrum Disorders from Other Outpatient Diagnoses in Youth
We compared 2 rating scales with different manic symptom items on diagnostic accuracy for detecting pediatric bipolar spectrum disorder (BPSDs) in outpatient mental health clinics. Participants were 681 parents/guardians of eligible children (465 male, mean age = 9.34) who completed the Parent General Behavior Inventory-10-item Mania (PGBI-10M) and mania subscale of the Child and Adolescent Symptom Inventory-Revised (CASI-4R). Diagnoses were based on KSADS interviews with parent and youth. Receiver operating characteristic (ROC) analyses and diagnostic likelihood ratios (DLRs) determined discriminative validity and provided clinical utility, respectively. Logistic regressions tested for incremental validity in the CASI-4R mania subscale and PGBI-10M in predicting youth BPSD status above and beyond demographic and common diagnostic comorbidities. Both CASI-4R and PGBI-10M scales significantly distinguished BPSD (N=160) from other disorders (CASI-4R: Area under curve (AUC) = .80, p .05). Diagnostic likelihood ratios indicated low scores on either scale (CASI: 0ā5; PGBI-10M: 0ā6) cut BPSD odds to 1/5 of those with high scores (CASI DLRā = 0.17; PGBI-10M DLRā = 0.18). High scores on either scale (CASI: 14+; PGBI-10M: 20+) increased BPSD odds about fourfold (CASI DLR+ = 4.53; PGBI-10M DLR+ = 3.97). Logistic regressions indicated the CASI-4R mania subscale and PGBI-10M each provided incremental validity in predicting youth BPSD status. The CASI-4R is at least as valid as the PGBI-10M to help identify BPSDs, and can be considered as part of an assessment battery to screen for pediatric BPSDs
The Interaction of Ī±B-Crystallin with Mature Ī±-Synuclein Amyloid Fibrils Inhibits Their Elongation
Ī±B-Crystallin is a small heat-shock protein (sHsp) that is colocalized
with Ī±-synuclein (Ī±Syn) in
Lewy bodiesāthe pathological hallmarks of Parkinson's
diseaseāand is an inhibitor of Ī±Syn amyloid
fibril formation in an ATP-independent manner inĀ vitro. We have
investigated the mechanism underlying the inhibitory action of sHsps, and here
we establish, by means of a variety of biophysical techniques including
immunogold labeling and nuclear magnetic resonance spectroscopy, that
Ī±B-crystallin interacts with
Ī±Syn, binding along the length of mature amyloid
fibrils. By measurement of seeded fibril elongation kinetics, both in solution
and on a surface using a quartz crystal microbalance, this binding is shown to
strongly inhibit further growth of the fibrils. The binding is also demonstrated
to shift the monomer-fibril equilibrium in favor of dissociation. We believe
that this mechanism, by which a sHsp interacts with mature amyloid fibrils,
could represent an additional and potentially generic means by which at least
some chaperones protect against amyloid aggregation and limit the onset of
misfolding diseases
